Soil nematode biomass in relation to vegetation production and environmental factors in tropical irrigated upland and lowland rice fields.

(…) The dead root and stubbles, constituting the mulched materials, disappeared at the rate of <70% during Kharif crop and <40% in the Rabi crop. The mean monthly nematode dry mass was 43.24±29.1 mg m −2 with a turnover of 4.7 for the upland and 5.41±2.67 mg m −2 with a turnover value of 3.8 for the lowland. Out of the various factors influencing nematode biomass viz. temperature, soil moisture and vegetation etc. temperature proved to be more important
